Model R96 Radar Transmitter
2.4.1.3 Obstructions
Almost any object that falls within the beam pattern will cause
reflections that may be misinterpreted as a false liquid level.
Although PULSAR Model R96 has a powerful Echo
Rejection routine, all possible precautions should be taken to
minimize false target reflections with proper installation and
orientation. Refer to section 2.4.2.3 for additional information.
2.4.1.4 Nozzles
Improper installation in a nozzle creates “ringing” that will
adversely affect measurement. The antenna should always be
mounted so the active section of the antenna is a minimum
of 0.5" (13 mm) outside the nozzle. Antenna extensions are
offered to allow the PULSAR Model R96 transmitter to
work reliably in nozzles with “L” dimensions of 25 mm
(1"), 100 mm (4"), 200 mm (8") or 300 mm (12").
Standard antennas (no extension) are shown below for refer-
ence. See Section 3.7.6 for dimensional drawings of all
antenna designs including nozzle extensions.
